How to use Draw Advanced Fractals
- 1. Pick a fractal type. Choose Mandelbrot set, Julia set, Apollonian gasket, Padovan spiral or Rauzy fractal from the Fractal setting. Each follows a different mathematical rule and produces a distinct shape.
- 2. Set the canvas size and iterations. Enter Width and Height in pixels for the output image, and set Iterations to control how much detail the escape-time or recursive calculation resolves before stopping.
- 3. Tune Julia set parameters if selected. When drawing a Julia set, set Julia c (real) and Julia c (imaginary) to choose the complex constant that shapes the fractal's particular structure.
- 4. Download the rendered image. Click generate to render the fractal as a PNG file, then download it for use as a wallpaper, print, or illustration in a math write-up.
When to use Draw Advanced Fractals
Draw Advanced Fractals renders five classic fractal types, Mandelbrot, Julia, Apollonian, Padovan and Rauzy, as downloadable PNG images. Use it for math visualization, generative art, or exploring how each fractal's parameters change its shape.
- Illustrating complex dynamics for a lesson. A course on complex numbers or dynamical systems needs a clear Mandelbrot or Julia set image, and rendering one at a chosen resolution gives a ready-to-use classroom illustration.
- Exploring Julia set parameter changes. You want to see how varying the c constant reshapes a Julia set, so you render several images with different real and imaginary values and compare the resulting patterns.
- Generating art for a print or poster. You need a high-resolution fractal image for a print, and setting a large width and height with enough iterations produces a detailed PNG suitable for enlargement.
- Studying circle-packing fractals. A geometry exploration into the Apollonian gasket benefits from a rendered image showing how nested circles tangent to their neighbors fill the plane.

About the Draw Advanced Fractals tool
Draw Advanced Fractals runs as plain JavaScript in your browser tab, with no server behind it. Padovan, Apollonian, Mandelbrot, Julia, Rauzy. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Math Tools section, 234 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 7 settings, including Fractal, Width (px), Height (px) and Iterations, and the result refreshes the moment you change one. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. 3 worked examples further down the page show exactly what the tool produces for real inputs.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Draw Advanced Fractals free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Does the generator send anything to a server?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How do I get a different result?
Run the generator again. Each run is computed fresh on your device, and any options you change are applied to the next result immediately.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I save the output?
Click the Download button once the result is ready. The file is built in your browser's memory and handed straight to your downloads folder, without passing through a server.
